To all whom it may concern:

Be it known that I, WILLIAM ALBERT RoHR, of the town of Sorel, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Air-Compressing Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has for its object to secure the maximum compressive energy from dynamic force.

The invention may be said briefly to consist of a weight ofiering relatively slight resistanceto movement and having a high degree of compressive energy represented by dead-weight and a series of receptacles, each adapted to contain a body of fluid to be compressed, depressible means being located in the path of and adapted to be compressed by said weight as it moves, while intermedial means are operated by said depressive means and adapted to compress the fluid in said receptacle.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which similar reference characters indicate the same parts, and wherein Figure 1 is a'plan view of the base and rails of an air-compressing apparatus constructed according to my invention. Fig. 2 is a longitudinal vertical sectional view thereof, taken on line A A, Fig. 1. Fig. 3 is a transverse vertical sectional view, and Fig. 4 is a side elevation of my complete apparatus.

The foundation or bed I) for supportingmy improved apparatus is preferably made of concrete, and a pair of longitudinals 0, one located near each side edge thereof, support a pair of guiding-rails (1, preferably of triangular cross-section. These rails are supported at a sufficient height above the bed or foundation to accommodate a series of cylinders c, pivoted at their lower ends, as at f, to the bed and containing pistons h, with piston-rods i, projecting through the upper ends of the cylinders and having bearing members j, each in the form of an arc, corresponding in radius to the main compressive member, to be presently described, and such bearing members having antifriction-rollers j set therein. These cylindersare preferably arranged in staggered relation, and a pair of props or supports 7c are located at opposite sides of each cylinder and are carried rigidly by the bed in a line extending diametrically through the c linders and longitudinally to the rails. Anexpansile spring m yieldingly retains each bearing member and with it the piston-rod and piston in its uppermost position.

My improved compressing member consists of a rolling weight, preferably in the form of a solid cylinder n, constructed of material of great specific gravity and being of a length to extend completely across the space between the rails, A pair of wheels 0 are secured rigidly to the ends of this rolling weight and have their peripheries formed with angular grooves to receive the rails. The perimeter of the cylinder has a series of sprocket-teeth encircling same about midway of its length, and the upper strand of an endless chain, looped at its opposite ends over driving-sprockets p, engages the uppermost teeth in order that when these drivingsprockets are rotated the weight will be caused to roll from one end to the other of the rails and back again when the direction of rotation is reversed.

In the operation of my compressor the cylinders turn on their pivots as the roller passes over them, so as to keep the concave faces of the bearing members j turned toward the roller.

What I claim is as follows:

1. In an air-compressing apparatus, the combination with a base, a weighted rotary member adapted to rest upon such base, and means for rolling the said member to and fro, of a cylinder, means pivotally supporting such cylinder below the surface of the said base, means for supporting the cylinder in an angular position facing the end of the base from which the member rolls, a piston movable in the cylinder, a piston-rod connected at one end to the piston, means yieldingly supporting the said piston with the opposite end of the piston-rod normally above the level of such surface and in position to be acted upon and depressed by the Weighted member, the said cylinder being adapted to oscillate in a plane parallel to the direction of travel of the rotary member and move with the said member While the latter acts upon the piston-rod.
